Specification of Letters Patent.

Patented Mag 19, 1908*.

Application filed. Iderch 29; 1907. Serial No. 385,292.

citizen of the United States, residing at Lesexternal atmosphere, but inthe aforesaid admixture; and to carr mgton, in the count 1 of Bichlandand State of Ohi0, .have invented certain new anduseful Improvements inProducer-Gas Apparatoe, of which the following is a specification.

My invention relates to improvements in what are known in this art asgas-producer alpparatus, more especially regulating devices t ierefor.its objects are principally to pro- Vide for controlling theproportionate admixture oi the steam and the air-hlast as the same aredelivered or fed to the ash-pit of the producer; to advantageously useother Wise unfit liquids or Water in eii'ecting the out the purposes ofthe invention in sup 0, expeditious and eii'ective manner.

Said invention consists or certain features or instrumentelitiessubstantially as herein.- ai'ter fully disclosed and specificallypointed out by the claims. I

In gas producer epperatus for generating fuel-gas from carbonaceousfuels and particularly such as are desig ed to hirnisn gas forpower-purposes it is of o utmost importones to control the proportion ofsteam or vapor carried along with th blast for delivery into the ash-pitof the u door.

My invention or apparar is, as will be clearly disclosed later, intoided to accomplish in a perfectly simple and automatic manner theaforesaid result and control the saturated and heated air for thatpurpose, it being based upon the Well known physical fact that for anygiven to. 'perature air Will hold in suspension in the it ill of vapor acertain definite proportion of water.

In the accompanying drawiu illustrating the preferred embodiment oi .oiyinvention--- igure 1 is a sectional elevation in part of the inventionwith parts broken away. F 2 is a plan view of the same.

In carrying out my invention, 1 provide a suitable tank 1 preferably ofshectunetal, with a tightly closed bottom and a like top, which tankhas, near its bottom so airiulet 2 and a Waste-water outlet 3. :5 airill-st, in the suct1ontype"of producer, simply opens to the L pressureeof producer it has applied to it a suite blower of any usual orpreferred pattern.

l l l l I 7 for controlling the Watensupply therethrough as presentlyfully disc. used, the same haviiilg a downwardextending ate- 8 to thelower end of which is fixed a tlaerrno stat 10, at one end. The oppositeof s: thermostat is fixed to and supported in position by a bracket-bar11 suitably connected to the pipe 5. It will be noted that thevalve-stem 8 depends through the upper end of the tubular extension orpipe 4 and has its lower end arranged therein, and that the thermostatis disposed princioal'ly Within the air outlet-pipe 5, with one em.extending into the pipe 4, Where it connects with the valvestem, thusproviding for exposing said thermostat to toe action of any varyingte1nperatures which ma r prevail Within said outlet pipe, as present ymore fully made apparent.

The tank 1 is suitably filled in with numerous wooden slats or pieces12, or other suitable material, laid crosswise or checkerwork fashion,to form an extended superficial area therein, over which the water, whenturned on at the valve 7 is caused to flow, the same finally leaving thetank via the waste-pipe 3. It will tl'ierefore be noted that the air,admitted through the air-inlet 2 of the tank 1 by suction or pressure asthe case may be, into the latter, will become suitably saturated withthe hot-water and its tem perature be raised as it is thus allowed orcaused to ass over the extended superficial area, resu ting from theassemblage of wooden slats, and livered out through the pipe S andfinally into the ash-pit of the gas-procucer, where, to- I gether withthe steam or vapor thus generated, the same will be delivered to thepro-v (.lucer.

is in communication with the external at mosphere, the action of theproducer will draw cool air through said inlet and into the tank 1 andupward through the latter, and into contact with, or over the filled-inwooden slats or'pieces of other suitable material, the air beingdischarged through said pipe to the producer. Simultaneously a stream ofhot water of about the temperature before noted is discharged from theipe 6 under the control of its valve 7 into t e up per part of thetank 1. Said ot Water stream flows downward over said wooden slats, orother material used, wetting the latter and exposing a large area orsurface of hot water to the incoming air. The water is in this waycooled, parting with its heat, and heating the air, the latter alsobeing saturated with the moisture up to the limit of the carrying caacity of its temperature at the time of disc arge. This warm moistureladen air, in passing from the apparatus will come into contact with thethermostat 10. The latter is so adjusted as to close the valve 7 andaccordingly cut off the hot-water supply when the temperature of the airexceeds a certain definite limit andto open the valve when thetemperature descends below said It is apparent that it is thus madepossible to maintain in the outgoing an a uniform temperature andconsequently a uniform per cent. of'suspended moisture reardless ofvariations in the amount of air For it is plain that should thetemperature fall below the predetermined point, which it may be desiredto maintain, the thermostat 10 will open the valve 7 and permit a muchlarger supply of hot water to the tank 1, whereby the temperature andmoisture contents of the air supplied to the producer will be againbrought to the standard condition. If on the other hand the temperatureof the air and the consequent per cent. of susplended moisture shouldincrease beyond t e desired limit, the thermostat would ave the effectto immediately close the valve 7 thus cutting off the supply of waterand al lowing the temperature to again fall to the reuired point. Inthis way a uniform condition of temperature and moisture of the outgoing air is maintained at all times and variations in the quantity ofblast delivered. are automatically provided for. The average amount ofmoisture carried in the air may be readily regulated b accordinglyadjusting the length of the va vestern 8, thus providing for changingthe temperature at which the valve 7 may be set for closing.

It is understood that any other convenient form or make of thermostatmay be employed herein in lieu of that shown. F or ordinary producer gaswork it is found that it is convenient to carry about one part by weightof moisture and nine parts by weight of air.

- receiving means ssasse For this proportion it would be necessary tocarry a temperature for the outgoing air of approximately-one hundredand thirty degrees Fahrenheit. Among the special advantages of thisarrangement may be mentioned the fact that by its employment it isossible to make use of Waters for this purpose Which are very impure,and which could not be used in a steam boiler for suppl ing steam in theordinary way on account of the large amount of deleterious minerals heldin sus ension.

W ith this apparatus it would he obviously possible to use sea-water oralkaline waters, since the amount of evaporation would not be sufficientto cause a precipitation of solid matter; even in the event of some ofthe more solid matters precipitated no harm could result to theapparatus, and the de osited matter could be very readily remove ,Iclaim 1.
